5962-9451305MPA

Overview

The Texas Instruments part number 5962-9451305MPA is a military-grade variant of the UCC1805 low-power BiCMOS current-mode PWM controller. It operates within a temperature range of -55°C to 125°C and utilizes an 8-pin Ceramic Dual In-Line Package (CDIP-JG). The device supports switching frequencies up to 1000 kHz and provides a maximum output drive current of 1A. It functions as a positive output step-up, step-up/step-down DC-DC controller suitable for boost, flyback, and forward converter topologies.

Feature Summary

• Low-power BiCMOS technology implementation
• Current-mode PWM control architecture
• Military-grade environmental qualification

Applications

• Boost converter regulation
• Flyback converter systems
• Forward converter designs

Procurement Notes

Verify that the specific suffix MPA confirms the required military grade qualification and ceramic package type. Ensure the supplier provides traceability documentation consistent with the 5962 prefix standards. Confirm the revision level matches the target design specifications before integration into production workflows.

Selection Notes

Select this component when high reliability and wide temperature operation are mandatory. The CDIP package offers robust mechanical integrity for harsh environments. Current-mode control simplifies compensation network design compared to voltage-mode alternatives in similar power applications.

Part Context

This part belongs to the UCC180x family of low-power PWM controllers. It shares functional characteristics with commercial variants like the UCC1805N but differs in packaging and environmental testing protocols. The 5962 prefix indicates it is a direct buy or microcircuit manufactured under government contract specifications.

Replacement Considerations

Commercial equivalents such as UCC1805N offer identical electrical functionality but lack military qualification. Verify that the pinout and thermal characteristics remain compatible if substituting with other UCC180x series devices.
